ed on the `bottom 21,"for' a Apurpose hereinafter described. The conduit '26 extends for several lengths, as indicated at 30, between the front-wall 3| of the-carbonator tank 29 andthe'front wall 32 'v of the ice-box 2I, and then extends upwardly-'adjacent the end wal1'33 of the carbonator tank 29, terminating in an elbow 34 threaded to 4a reduced conduit 35 v'vliich 'extends' downwardly in a coil,

' "as indicated .at 36, between the rearwall- 31 of `the 'carbonatortank 29'and the rear wall 38 of the ice-box 2|, andv thence upwardly and transverselyabove the cover 3901 the carbonator tank 29, terminating in a valve casing 40. The con- "duits as arrangedprovide a lengthyr passage for the water prior toits use, and the water iscooled to a low temperature by covering the conduit coil 36 with cracked ice or the like.

The valve casing 40 (see Figure 4) supported by a bracket 4| mounted on the cover 39 and comprises a reduced port 42 (see Figure 14) communicating Vat one end with the conduit and a't the'opposite end with a valve chamber 43, which communicates with a chamber 44.through a reduced port 45, provided with a valve seat 46 engageable by a valve 41 threaded to the inner end of areciprocating valve stem 48 extending through a gland nut 49 v'threaded in the valve casing 48. Disposed about the valve stem 48 is uid into the conduit 52 and its connected conduit members.

A coupling 51 is screw-threaded'to thel sleeve 53 and embraces the one way valve 56 in' spaced relation, forming a` chamber 58 thereabout, andthe coupling 51 is provided with a reduced port 59 which communicates with a conduit 6|l threaded into the other end of the'coupling 51, and the conduit 68 in turn communicates with the upper portion of an agitator paddle housing 6| mounted on the cover -39 of the carbonator tank 29 and communicating with the'interior of the carbonatorvtank 29, thereby providing conduit means traversing considerable distancewith respect to the area of theice-box 2| to convey water from the source of supply to the carbonator tank 29. -A carbonic gas conduit 62 (see Figure 4) has one end connected to the source of carbonic gas supply, not shown, and the other end 63 terminating in the carbonator tank 29 adjacent the bottom thereof beneath"the agitator paddle housing 6|. A pressure valve (not shown) for regulating the pressure from the carbonic gas` supply is set to deliver a constrant'ow of gas at a predetermined pressure; and a gas checkvalve 64 is inserted in the gas conduit 62 to prevent back-fiow of gas from the carbonator tank 29 and permit entrance of the gas into the carbonator tank 29.

is a flange 65 enclosing a boss 66, and the flange 65 is closed by a cover plate 61,.thus providing a. gear box 68 adapted/to be lled with oil or grease. Journalled in the boss66 is a shaft 69 carrying at one end an agitator paddle 10 secured thereto by a pin 1|. The agitator paddle 10 is adapted to rotate within thehousing 6| and isiprovided with vanes. 12 curved at their free ends, as at 13. Fixed to the. opposite end of the shaft 69, by a pin 14,' is a worm-gear 15 adapted to mesh. with a worm-wheel 16 secured to the midsection' of a shaft 11 which extends through opposite sides of the flange 65.

When rotative movement is imparted to the shaft 69, the agitator paddle 10 is rotated, and

- the curved vanes 12 lagitate the Water and carbonic gas inthe carbonator tank 29, causing the carbonicgas to permeate the water, producing a carbonated Water suitable for mixture with flavoring Syrups or for use unadulterated.

18|, of a fly-wheel construction 82.

Integral with the agitator paddle housing 6| Water traversing the water conduit means herein described is cooled to a low temperature Vbefore entering the carbonator tank 29 and prior to coming into` contact with the carbonic gas. I find that with my vmethod of preparing carbonated water by cooling the water prior to mixing with the carbonic gasA and then agitating the water and gas in a cold state, that a largerv amount of gas can be absorbed by the cold water than if the water were mixed at normal temperature with the gas; furthermore, the gas is .more completely absorbed.by .the cold Water,

thereby retaining the characteristics of carbonic gas in the water for a longerYJ period of time, than is obtained in the conventional method of carbonating water. v -One end of the shaft 11 is adjustably secure within one end of asleeve 19 (see Figure 14) by means of a s'crew 80, and the sleeve 19 is rotatably mounted within a cup-shaped member Secured to the flanged extremity of the cup-shaped member 8|, by means of screws 83, is a member 84,

having a-projecting boss inwardly threaded' -as at 86, adapted to receive the threaded end 81 of the sleeve 19, and provided with a pin 88 extending transversely therefrom into the. cup portion of the member 8|. The pin 88 is adapt ed to engage a stud 89 secured-to the member 84.

Adjacent the threaded portion 86 in the boss 85 is secured an outer ball race 90, and an inner ball race 9| -is secured to the end of the valve stem 48 by. a nut 92. Interposed between the races land 9| are balls 93 providing a ball i bearing arrangement which permit the fly-wheel valve stem-48, and prevent linear movement of the fly-wheel 82 along the valve stem 48. The outer end of -the boss 85 is closed by a plate 94 detachably secured to the boss 85v by screws 95,.

When the shaft 1 1 is rotated to the left, as viewed in Figure 14, the sleeve 19 also rotates to the left, but the fly-wheel 82 does not rotate, due to its inertia. However, the threaded movef ment of the sleeve 19 in the y-Wheel 82 causes -linear movement of the fly-wheel 82 to the right,

which in turn movesvthe valve stem 48 to the right' and closes the valve 41, preventing addi-n tional water entering the carbonator tank 29. 'Ihe threading movement of the sleeve 19 to the left is limited vby the pin 88 abutting the Aopposite side of the stud 89, as shown in broken linesin Figure 15, at `which time the ywheel 82-is positively engaged and rotates to the left with the sleeve 19. When the shaft 11 ceases to rotate'the fly-Wheel 82 continuesto rotate,v

due to its inertia, and threads the ily-wheel 82 on tothe sleeve 19, causing' linear movement of the fly-wheel, 82 to the left, which' movement is limited -by the pin 88 abutting the stud 89,

as shown in solid'lines in Figure 15. This latter .82 to rotate freely about the sleeve 19 and the threaded'advancement to the left, as viewed in- Figure 14, is suii'icient to pull the valve stem y .48 tothe left and openy the valve 41, permitting water to ow to the carbonator tank 2'9.

A motor 96 isirnounted on a platform 91 and the shaft 98 of the motor 96 is connected to the lencl of theshaft 11. When the motor 96 isoperating, it imparts rotative movement to the shaft v11 which in turn actuates the agitator paddle 10 and the valve stem 48, as lhereinbefore de scribed.. l

I- have also made provision for dispensing unadulterated carbonated water directly from the The mechanism employed in' that connection comprises a dispensing unit 203 having a faucet 204 disposed between the units 200 and 20| and threaded to the front wall of the cabinet |2, and is provided with a suitable valv'e 220 operated in the usual manner by a faucet handle 205. The faucet 204 has a reduced outlet 206 in a depending nozzle 201 which communicates with an enlarged channel 208, terminating in a pipe 209 having one end threaded to the end of the faucet 204 and the other end terminating within the carbonator tank 29 in direct communication with the carbonated water therein. The inner end of the faucet 204 is secured to the inner'surface of the front wall of the ice-box 2| Vby a gasket and nut arrangement as indicated at 2|0. The inner end of the pipe 209 is lsecured to the carbonator tank 29 by a gasket and nut ar-v rangement as shown at 2| I.

When the faucet handle 205 is move'd forwardly, the carbonated water is dispensed with considerable force through the reduced outlet 206. The force of the ejection being suicient to disintegrate ice-cream, and to completely mix avored `is secured to lthe frame I0, to support glasses, or the like, during the dispensing operation.
